3.6  SP Ramp Set Up Group 
Introduction 
Set Point Ramp, Set Point Programs and Set Point Rates can be configured in this group. 
A single Setpoint Ramp [SP RAMP] can be configured to occur between the current local 
setpoint and a final local setpoint over a time interval of from 1 to 255 minutes.  
A Set Point Rate [SPRATE] lets you configure a specific rate of change for any local 
setpoint change. 
A single Set Point Program [SP PROG] with up to 20 segments can be configured. 
For more information on Set Point Rate, Ramp and Programming, see Sections 4.27 
through 4.30. 
You can start and stop the ram
p/program using the 
RUN/HOLD key. 
PV Hot Start is a configurable feature and means that, at initialization, the setpoint is set 
to the current PV value and the Ramp or Rate or Program then starts from this value.
